VIST vs YPF: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: VIST is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. VIST and YPF share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined VIST and YPF exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Vista Energy, S.A.B. de C.V. is an oil and gas exploration and production company incorporated in Mexico that operates almost entirely in Argentina, where it is the leading independent (non-state) producer in the Vaca Muerta shale formation in the Neuquen basin. It was founded in 2017 by Miguel Galuccio, a former chief executive of Argentina's state oil company YPF, and it makes money by drilling horizontal shale wells, producing crude oil and natural gas, and selling that output into the Argentine domestic market and, increasingly, export markets. Vista is a growth-focused pure-play: it reinvests most of its cash flow into new wells and acreage rather than paying a large dividend.

YPF Sociedad Anonima is Argentina's integrated oil and gas company: it explores and produces crude and natural gas, runs the country's largest refining system, and sells fuel through a nationwide service station network under the YPF brand. The Argentine state holds 51% of the equity, the remainder trades publicly, and the ADRs have been listed on the NYSE since the 1990s. Over the past three years the company has been reshaping itself around unconventional assets, selling or handing back dozens of mature conventional blocks (the Andes divestment program) and pushing capital into Vaca Muerta, where lifting costs in its core shale hub run near $4 per barrel of oil equivalent against roughly $8.8 consolidated. It also holds stakes in midstream and export infrastructure, including the VMOS crude pipeline to an Atlantic terminal, and has signed partnerships with Eni and Shell around a floating LNG project aimed at monetizing Argentine gas for export.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• VIST drivers: Vaca Muerta production growth; La Amarga Chica and acreage expansion.
• YPF drivers: Vaca Muerta volume growth; Export infrastructure and the shift to dollar revenue.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Vista's earnings are highly cyclical because they rise and fall with global oil and natural gas prices, which the company does not control. For YPF, argentine sovereign and policy risk sits above everything else: the state owns 51%, so board composition, fuel pricing, export permits, and currency access are all subject to the politics of the day, and past administrations have intervened in domestic prices in ways that cut refining margins.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick VIST if you believe its drivers more; YPF if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the VIST and YPF guides.

VIST. As of April 2026 Vista traded at a low single-digit-to-high-single-digit trailing earnings multiple (around 7x), a discount that reflects oil-price cyclicality and Argentine country risk rather than weak growth. Revenue, EBITDA, and reserves all grew sharply in 2025 on rising production, while enterprise value of roughly $7.6 billion reflected about $3.3 billion of net debt on top of the equity value. Figures are approximate and change with oil prices, the share price, and each quarterly report.

YPF. On annualized recent EBITDA the enterprise value works out to roughly four times, a level well below US shale independents of similar growth, and the gap is the market's price for Argentine country risk rather than a judgment on the wells. Reported earnings per ADR are noisy because 2025 carried large impairments from the conventional asset exits, so trailing price to earnings ratios on screeners can be misleading in either direction. YPF pays no dividend on the ADRs at present, with cash directed to capex and debt reduction.

Headline figures (approximate, APRIL 2026): VIST shows revenue (fy2025) ~$2.47 billion (+50% YoY), net income (fy2025) ~$719 million, adjusted ebitda (fy2025) ~$1.6 billion (~65% margin), production (q1 2026) ~135,000 boe/d (+67% YoY); YPF shows revenue (ttm) ~$19 billion in US dollars (screeners that show Argentine peso figures will look wildly different), adjusted ebitda (q2 2026) ~$2.8 billion, an all-time quarterly record, at ~43% of revenue, net income (q2 2026) ~$1.2 billion, the second highest quarter on record, market cap ~$21 billion (~391 million ADRs, ADR price recently near $50).

VIST and YPF are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
